Series War UL/FM Air Release Valves
Brand: Henry Pratt CompanyAirPro Max® Series WAR UL Listed and FM Approved Air Release Valves are designed to vent trapped air that collects at high points in a pipeline.
These valves continuously release air from systems thereby preventing large air pockets to form which can cause damaging pressure surge to the system.
In many installations lacking Air Release Valves, large pockets of air in the pipeline will cause power consumption to increase, and flow to decrease, possibly completely.
Another possible result of excessive air accumulation is the inexplicable pipeline rupture that is mistakenly attributed to ground settling or defective pipe.
In reality unusually large air pockets can greatly increase the pressure of normally occurring surges to the point where sudden stops and starts of flow can cause a pipe to rupture.
